Thanks for this, was not aware this was added. Though better would be to have a global option for this, and a tunable whether to filter this completely or only for persistent storage.

For the last few days I have been monitoring journald with iotop and found in my case storage use was not excessive at the moment. And there are rate limit options, but I'd really like there to be system-wide filtering options.

For servers I rarely see journald persistence enabled while it is actually very valuable for debugging crashes and other issues. Way easier than regular log files. Though also more fragile and more difficult, so improvements are very welcome.
